AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hi Karel,

This looks good to me. A local comparison of the 3dcalc-computed t to those output be 3dttest++ showed an exact match (using your exact expression with a change for DoF).

Note that if you are starting with volume #0 from 3dttest++, that will be an effect (beta) magnitude, not a z-score. 3dcalc will process all volumes using the same expression.
